Looks like Alia Bhatt's close friendship with her Brahmastra co-star Ranbir Kapoor hasn't gone down well with BFF Katrina Kaif, who's also Ranbir's ex.

Lately, there has been much buzz around Ranbir and Alia's newfound friendship.

When asked about this, Alia had earlier told Hindustan Times, "Even I get really confused when I read such things, but I strongly believe that 'silence is golden'. It's not as if I'm never going to have a personal life. I will and I do have one, but I feel its called 'personal' for a reason. That's why it will always stay close to me," Alia told Hindustan Times.

However, it seems like Katrina needs to be convinced, more than anyone else.

Katrina and Alia have been close friends. In fact, just the other day, Alia expressed her desire to work with Katrina.

If sources are to be trusted, cracks in the friendship appeared in Alia and Katrina's friendship, after Alia posted a photo with Ranbir on Instagram.

A source told Pinkvilla, "The entire cast and crew have been talking about RK and Alia's closeness while filming Bramhastra. Katrina got to know about it from some common friends who were working on the film. She is upset and would have appreciated had Alia told her about her closeness with Kapoor."
